CARPET-CLEAN ER.

SPECIFICATION forming part of Letters Patent No. 585,843, dated July 6,1897..

Application filed May 8, 1896. Serial No. 590,706. (No model.)

To @ZZ whom it may concern:

Be it known that I, KELLY GIRvIN, of Brooklyn, in the county of Kingsand State of New York, have invented a new and Improved Carpet- CleaningMachine, of which the following is a full, clear, and exact description.

The object of the invention is to provide a carpet-cleaning machineconstructed in an exceedingly simple and durable manner and ro so that acarpet may be expeditiously and conveniently fed through the machine andbeaten and thoroughly cleaned without injury to the pile of Brussels orlike carpets and with- Y out tearing or injuring in grain or similarcarpets.

Afnrther object of the invention is to provide a machine so constructedthat the dust incident to beating and cleaning will be removed from thebody of the machine, and

zo consequently from the portion of the carpet being cleaned, as soon asthe dust hasbeen ,extracted from said carpet.

The invention consists in the novel construction and combination of theseveral 2 5 parts, as will be hereinafter fully set forth,

and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indi- 3ocate corresponding parts in all the figures.

Figure 1 is a horizontal section through the machine. Fig. 2 is avertical section taken about centrally through the machine on the line 22 of Fig. l. Fig. `3is a transverse sec- 3 5 tion through the machine ata point near its center, and Fig. 4 is a transverse section slightlymodified in its construction from that shown in the other figures.

In carrying out the invention a box-body,

4o forminga chamber A and made of any suitable material, is supportedordinarily by uprights 10, connected at the top by cross-bars 11, andthe said uprights below the box or chamber may be connected and bracedin any 45 suitable or approved manner. At what may be termed the frontend of the box or chamber A an opening 12 is made, and at the top andbottom of said opening slideways 13 are formed, in which gates 14 areheld to travel,

5o the said gates being adapted to entirely or partially close theopening 12, as shown in Figs. 1 and 2. The opposite or outer end of thebox or chamber A is open and is provided with a tapering orsubstantially conical extension 15, having an opening in its end wall incommunication with an exhaust-fan 16, which is driven from a suitablepulley 10a by means of a belt 1Gb, carried to any source of power, andthe exhaust-fan is supported upon a base 17 of any approvedconstruction.

Uprights 17a are located at the central end portions of the chamber orbody A, as shown in Figs. 1 and 2, and in these uprights the trunnionsof a shaft 18 are journaled, the said shaft extending the entire lengthof the chamber. This shaft is ordinarily made polygonal incross-section, as shown in Fig. 3, and a number lof beater-arms 19 aresecured to the bottom of the shaft, extending beyondboth sides thereof,and the various beater-arms are connected by slats 20, or theirequivalents, the said slats being in suitable number and preferablyequally distributed at each side of the shaft.

The shaft 1S is given a rocking motion, preferably through the medium ofa crank-arm 21, placed ordinarily near its rear end, the said crank-armbeing pivot-ally connected with apitman 22, which pitman is pivoted upona crank-pin 23, located on a crank-disk 24, placed upon a shaft anddriven by a pulley 26, connected by a belt 26@ with suitablev power.Immediately below the rockshaft 18 a roller 27 is journaled in theaforesaid uprights 17, as shown in Figs. 2 and 3, and at each side ofthe box or chamber A a door A is located, having a hinge connection withthe upper portion of the said chamber or box, as shown in Fig. 3, andthese doors extend practically from end to end of the chamber, but areof such width that an opening 28 is provided between their lower endsand the lower bottom side wall 29 of the chamber, which latter side wallhas a curved or bev eled upper edge. Cords, ropes, or cables 30 arepreferably detachably secured to the bottom of the chamber or box A ateach sideand are carried inward over the inclined surfaces of the bottomside walls 29 and over the roller 27, as is particularly shown in Fig.3, the spaces 28 being normally closed by strips 31 of cloth or likeyielding material attached to the inner faces of the said doors A andextending sufliciently far downward therefrom IOS to engage with andextend downward alongside of the bottom side walls 29 when the machineis not in use.

At each side of the bottom portion of the supporting-framework of thebox or chamber A an extension-frame 32 is constructed, and in eachextension-frame a shaft 33 is journaled, preferably polygonal incross-section except where it enters its bearings. Chains, cables, orropes 34E or the equivalents of the same are attached to the shafts 33at given intervals in their length, and each chain or cable 34 isprovided with a hook 35 or other form of clamp at its free end. Thesehooks or clamps are engaged with the ends of the carpet B to be cleaned,the carpet being rolled upon one shaft and then passed pile downwardthrough the opening 2S on that side into the box or chamber between theflexible extension 3l of the door at that side and the adjacent bottomside wall 29, over the cords or cables 30, and consequently over theroller 27, thence out through the opposing space 28 Vin similar manneras when entered to an attachment to the opposing shaft 33, as shown inFig. 3. The winding-shafts 33 are provided with hand-wheels 35n at oneor both of their ends, in order that they may be manipulated by hand, ifdesired, but they may be operated by power.

In the operation of this form of the machine, the carpet being passed`through the body or chamber of the same, as shown in Fig. 3, when therock-shaft is in motion the beaterarms and connecting-rails willalternately engage with the carpet at opposite sides of the roller 27and will force the dust and foreign matter out therefrom, and thismotion is continued throughout the entire cleaning of the carpet, andwhen one section has been cleaned the said cleaned section is rolledupon the winding-shaft 33, to which the outer end was attached, bringinganother surface under the action of the beaters, but as soon as the dustis driven from the carpet it is carried out from the box or chamber bythe exhaust-fan sucking the air from the opening l2, regulated by thegates 14.

Instead of cleaning one carpet only at one operation, two carpets may becleaned at the same time, as shown in Fig. 4. In this form of themachine two doors are employed at each side of the chamber or box A, anupper small door A2 and a lower small door A3, both being attached to alongitudinal support A4, and a space 28 is made to intervene the upperdoor and the upper portion of the box. and the lower door and the lowerportion of the box. The upper spaces, however, are normally closed bystrips 3S, of rubber or a like material,

lsecured to the upper door, while a fabric or similar substance 3 anormally closes the lower spaces, being attached to the lower door. Oneof the carpets, B, is passed through the machine in the mannerheretofore described and the other carpet, B, is passed through themachine at the upper side openings and over a second roller 39, locatedover the rockshaft, the pile or wearing surface of the carpet facingdownward, and the beater-arms 19 are in this instance provided withslats 2O at both top and bottom.

In the operation of this form of the machine the two carpets will besimultaneously struck by opposing beater-arms, and the dirt from theupper carpet will fall upon the back of the lower carpet, and all of thedirt will be drawn out by the exhaust-fan. The cables 30 within the bodyor chamber are really supporting-cables and prevent the carpet fromsagging under the influence of the blows it will receive from thebeaters. When the upper carpet B has been introduced into the machine,the upper doors A2 may be kept in closed position by means of pins orbolts 37.

It will be seen that by providing a supporting-surface inclining towardthe axis of the beaters the beaters will have greater throw and thusdeliver a more effective blow in a chamber of given size than wouldbeaters operating in conjunction with a horizontal supporting-surface.

I-Iaving thus described my invention, I claim as new and desire tosecure by Letters Patent* l. A carpet-cleaning machine, comprising acasing having an inlet and outlet for the carpet at opposite sides, asupport for the carpet of yielding material arranged within the casing,said support inclining from a central rest downwardly to the inlet andoutlet of the casing and having its edges secured to the sides of thesaid casing, and a rocking beater mounted adjacent to the center of thesaid support, substantially as described.
